Fixes#9797
### What problem does this PR solve?
Currently, error responses and certain result objects may include types
that are not JSON serializable (e.g., ModelMetaclass, functions). This
causes server crashes instead of returning valid JSON responses.
This PR introduces a robust serializer that converts unsupported types
into string representations, ensuring the server always returns a valid
JSON response.

### What problem does this PR solve?
This PR fixes a critical bug in the session listing endpoint where the
application crashes with an `AttributeError` when processing chunk data
that contains non-dictionary objects.
**Error before fix:**
```json
{
"code": 100,
"data": null,
"message": "AttributeError(\"'str' object has no attribute 'get'\")"
}
```
**Root cause:**
The code assumes all items in the `chunks` array are dictionary objects
and directly calls the `.get()` method on them. However, in some cases,
the chunks array contains string objects or other non-dictionary types,
causing the application to crash when attempting to call `.get()` on a
string.
**Solution:**
Added type validation to ensure each chunk is a dictionary before
processing. Non-dictionary chunks are safely skipped, preventing the
crash while maintaining functionality for valid chunk data.
This fix improves the robustness of the session listing endpoint and
ensures users can retrieve their conversation sessions without
encountering server errors due to data format inconsistencies.

### What problem does this PR solve?
When the `dataset_ids` parameter is omitted in the **update assistant**
request, Passing an empty array `[]` triggers a misleading
message"Dataset use different embedding models", while omitting the
field does not.
To fix this, we:
- Provide a default empty list: `ids = req.get("dataset_ids", [])`.
- Replace the `is not None` check with a truthy check: `if ids:`.
**Files changed**
`api/apps/sdk/chat.py`
- L153: `ids = req.get("dataset_ids")` → `ids = req.get("dataset_ids",
[])`
- L156: `if ids is not None:` → `if ids:`

### Type of change
- [x] New Feature (non-breaking change which adds functionality)
- Add type and boundary checks for conv["reference"] access
- Prevent KeyError: 0 when reference list is empty or malformed
- Ensure reference is list type before indexing
- Handle cases where reference items are None or missing chunks
- Maintains backward compatibility with existing data structures
This resolves crashes in /api/v1/agents/<agent_id>/sessions endpoint
when conversation reference data is not properly structured.
### What problem does this PR solve?
This PR fixes a critical `KeyError: 0` that occurs in the
`/api/v1/agents/<agent_id>/sessions` endpoint when the system attempts
to access conversation reference data that is not properly structured.
**Background Context:**
The `list_agent_session` method in `api/apps/sdk/session.py` assumes
that `conv["reference"]` is always a properly indexed list with valid
dictionary structures. However, in real-world scenarios, this data can
be:
- Not a list type (could be None, string, or other types)
- An empty list when `chunk_num` tries to access index 0
- Contains None values or malformed dictionary structures
- Missing expected "chunks" keys in reference items
**Impact Before Fix:**
When malformed reference data is encountered, the API crashes with:
```json
{
"code": 100,
"data": null,
"message": "KeyError(0)"
}
```
**Solution:**
Added comprehensive safety checks including type validation, boundary
checking, null safety, and structure validation to ensure the API
gracefully handles all reference data formats while maintaining backward
compatibility.
